Are you getting these from a salvage yard or an auto parts store? The guys at the auto parts stores will look up the part by application; the year, model, engine size, and manual or automatic transmission if there's a difference. Sometimes there will be a notation in their books that a part fits only those cars built before or after a certain date. They will ask you to look at the sticker on the car, usually on the back of the driver's door, to find the production date.
The guys at the salvage yards will start the same way by checking if they have a car identical to yours and if the half shafts are still on it. If they don't have an identical car they will look up your half shaft in a "Hollander Guide". That will give the part a three or four-digit code number that they look up in the back half of the book. There it will list all the other applications that use that same part, then they can check if they have any of those cars in their yard or if they have any of those shafts in storage.
Either way the next step is to compare the new one to the old one. If you brought the old one with you they will do that right there to be sure it's right. If there is a difference they will try to figure out what they looked up wrong. It is not unheard of for a rebuilt half shaft, or any other rebuilt part, to get boxed wrong or labeled wrong.
